So from PYI (R&D Marine) the pre-drilled port is for finishing by drilling and tapping for a set screw/lock bolt if the coupler does not have a keyway. In my case, I asked for the online seller to add a keyway so the pre-drilled hole serves no purpose. In smaller shafts they may not even advise the lock bolt or key. You can see the hole in this picture. download.jpeg <https://drive.google.com/file/d/1Fyr_C_h8W7ivd7UgJtOmmgpsxdKZdAHy/view?usp=drivesdk>
